Description of Related Art

With frequent commercial activities and the rapid expansion oftransportation logistics, people are more dependent on the mobilevehicle such as car or motorcycle. At the same time, drivers are payingmore and more attention to the protection of their lives and propertywhen driving, and therefore, in addition to the performance and thecomfort of the mobile vehicle, it is also considered whether the mobilevehicle to be purchased provides sufficient safety guards or auxiliarydevices. Under this trend, in order to increase the safety of vehicles,automobile manufacturers or vehicle equipment design manufacturers havedeveloped various driving safety protection devices or auxiliarydevices, such as rearview mirrors, driving recorders, a panoramic imageinstant displaying of blind vision areas, a global positioning systemthat records the driving path at any time, and etc.

In addition, with the rapid development of digital cameras and computervisions in daily life, the digital cameras have been applied to drivingassistance systems, hoping to reduce the accident rate of trafficaccidents through the application of artificial intelligence.

Take a conventional rearview mirror as an example, when a driver changeslanes or turns, most of the conventional rearview mirror is used toobserve and determine the presence or absence of objects outside of thevehicle. However, most of the rearview mirrors have limitations anddisadvantages in use under certain driving conditions. For example, whendriving at night, the driver's pupil is in an enlarged state in the darkenvironment just like the shutter of the camera for providing moreoptical signals to the optic nerve. In such a state, the driver's eyesare extremely sensitive to sudden light. Usually, the rearview mirrorreflects the front light from the overtaking or subsequent vehicles,which causes the driver to have a visual dizziness, so that the driver'svisual ability will be rapidly reduced in an instant, increasing thedriver's reaction time that front obstacles become visible.

Moreover, based on the structural design of the traditional car, all ofthe rearview mirrors have their own blind vision area in thecorresponding installation position, so that the driver cannotcompletely obtain the actual road information outside of the car via theimages shown by the rearview mirrors. In terms of safety designconsiderations, the conventional rearview mirror still has room forimprovements.

Furthermore, when the driver wants to change lanes, turn, or reverseduring driving, the driver must change the line of sight to see the leftor right rear view mirror to know the road environment of the singlelane. However, the viewable area provided by the left or right rear viewmirror does not help the driver to know the blind vision informationthat the left or right rear view mirror does not display. Sometimes, thedriver needs to turn the head directly to check the rear exteriorconditions of the vehicle, or by watching the rearview mirror within thevehicle to completely capture the static and dynamic scene outside ofthe vehicle. Therefore, in the above specific actions for driving avehicle, the driver needs to constantly change the line of sight toobtain the road condition information, and cannot pay attention to theroad conditions in all directions in time, which may cause a caraccident or a collision event.

Therefore, there is a need for the manufacturers to develop an imageoutput device to display an image with a wide viewing angle integratedby both of the visible area and the blind vision area of the interiorand exterior rearview mirrors to the driver, so that the driver couldobtain the road information of the surrounding environment of thevehicle by a single line of sight conversion, improving the drivingsafety.

The length of the contour curve of any surface of a single lens in therange of the maximum effective radius affects the surface correctionaberration and the optical path difference between the fields of view.The longer the profile curve length, the better the ability to correctthe aberration, but at the same time It will increase the difficulty inmanufacturing, so it is necessary to control the length of the profilecurve of any surface of a single lens within the maximum effectiveradius, in particular to control the profile length (ARS) and thesurface within the maximum effective radius of the surface. Theproportional relationship (ARS/TP) between the thicknesses (TP) of thelens on the optical axis. For example, the length of the contour curveof the maximum effective radius of the side surface of the first lensobject is represented by ARS11, and the thickness of the first lens onthe optical axis is TP1, and the ratio between the two is ARS11/TP1, andthe maximum effective radius of the side of the first lens image side.The length of the contour curve is represented by ARS12, and the ratiobetween it and TP1 is ARS12/TP1. The length of the contour curve of themaximum effective radius of the side of the second lens object isrepresented by ARS21, the thickness of the second lens on the opticalaxis is TP2, the ratio between the two is ARS21/TP2, and the contour ofthe maximum effective radius of the side of the second lens image Thelength of the curve is represented by ARS22, and the ratio between itand TP2 is ARS22/TP2.

For any surface of any lens, the profile curve length within a half theentrance pupil diameter (HEP) affects the ability of the surface tocorrect aberration and differences between optical paths of light indifferent fields of view. With longer profile curve length, the abilityto correct aberration is better. However, the difficulty ofmanufacturing increases as well. Therefore, the profile curve lengthwithin a half the entrance pupil diameter (HEP) of any surface of anylens has to be controlled. The ratio between the profile curve length(ARE) within a half the entrance pupil diameter (HEP) of one surface andthe thickness (TP) of the lens, which the surface belonged to, on theoptical axis (i.e., ARE/TP) has to be particularly controlled. Forexample, the profile curve length of a half the entrance pupil diameter(HEP) of the object-side surface of the first lens is denoted by ARE11,the thickness of the first lens on the optical axis is TP1, and theratio between these two parameters is ARE11/TP1; the profile curvelength of a half the entrance pupil diameter (HEP) of the image-sidesurface of the first lens is denoted by ARE12, and the ratio betweenARE12 and TP1 is ARE12/TP1. The profile curve length of a half theentrance pupil diameter (HEP) of the object-side surface of the secondlens is denoted by ARE21, the thickness of the second lens on theoptical axis is TP2, and the ratio between these two parameters isARE21/TP2; the profile curve length of a half the entrance pupildiameter (HEP) of the image-side surface of the second lens is denotedby ARE22, and the ratio between ARE22 and TP2 is ARE22/TP2. For anysurface of other lenses in the optical image capturing system, the ratiobetween the profile curve length of half the entrance pupil diameter(HEP) thereof and the thickness of the lens which the surface belongedto is denoted in the same manner.

With the movable carrier auxiliary system described above, the movablecarrier is allowed to follow the target vehicle or the lane marking tofurther improve driving safety.

A movable carrier auxiliary system of the present invention mainlyincludes a system design and an optical design, wherein systemembodiments will be described first.

With reference to FIGS. 1A to 1B, FIG. 1A is a block diagram of amovable carrier auxiliary system 0001 according to a first systemembodiment of the present invention. The movable carrier auxiliarysystem 0001 includes an environment detecting device 0010, a statedetecting device 0020, and a control device 0030.

The environment detecting device 0010 includes an image capturing module0011 and an operation module 0012. As shown in FIG. 1C, the imagecapturing module 0011 is disposed at a movable carrier 000A, e.g. avehicle, for capturing an environment image of the movable carrier 000Ain the traveling direction. The image capturing module 0011 includes alens group and an image sensing component, and the lens group includesat least two lenses having refractive power for imaging to the imagesensing component to generate the environment image. The conditions ofthe lens group will be described in the optical embodiments. The imagecapturing module 0011 is disposed on the geometric center line i of thebody of the movable carrier 000A, for example, at the center of thevehicle body in the lateral direction.

The operation module 0012 is electrically connected to the imagecapturing module 0011 to detect whether there is at least one of atarget carrier 000B and a lane marking 000C in the environment imagecaptured in the traveling direction of the movable carrier 000A andgenerate a detection signal.

The state detecting device 0020 is disposed at the movable carrier 000Afor detecting a moving state of the movable carrier 000A and generatinga state signal. With reference to FIG. 1B, the state detecting device0020 of the embodiment includes a steering angle sensor 0021, aninertial measurement unit 0022 and a speed sensor 0023. The steeringangle sensor 0021 detects a steering angle of the movable carrier 000A;the inertial measurement unit 0022 is used to detect an acceleration, atilt angle, or a yaw rate of the movable carrier 000A; and the speedsensor 0023 is used to detect a speed of the movable carrier 000A. Thestate detecting device 0020 outputs the state signal according to thedetection results of the speed sensor 0023 and the steering angle sensor0021 or the inertial measurement unit 0022. In practice, there may beprovided with at least one of the steering angle sensor 0021 and theinertial measurement unit 0022.

The control device 0030 is disposed at the mobile device 000A andelectrically connected to the operation module 0012 and the statedetecting device 0020. The control device 0030 is configured tocontinuously receive the detecting signal and the state signal, and uponreceiving the detection signal that there is the target carrier 000B orthe lane marking 000C in the environment image, the control device 0030could control the movable carrier 000A to follow the target carrier 000Bor the lane marking 000C according to the detection signal and the statesignal.

In this embodiment, the moving state detected by the state detectingdevice 0020 includes at least the moving speed of the movable carrier000A. The control device 0030 controls the movable carrier 000A tofollow the target carrier 000B or the lane marking 000C only when thecontrol device 0030 receives the state signal that the moving speed ofthe movable carrier 000A is faster than a starting speed and thedetection signal that there is the target carrier 000B or the lanemarking 000C in the environment image. The starting speeds may be setaccording to the condition in the environment image. For example, whenthere is the target carrier 000B in the environment image, the startingspeed is not less than 30 K/mh; and when there is not the target carrier000B in the environment image but there is the lane marking 000C in theenvironment image, the starting speed is not less than 10 K/mh.

In addition, the movable carrier auxiliary system 0001 further includesa warning device 0040 electrically connected to the control device 0030.The warning device 0040 is controlled by the control device 0030 togenerate a warning message to prompt the driver. The warning device 0040sends the warning message to generate at least one of the correspondinglight and sound. The warning device includes a buzzer or/and a lightemitting diode (LED), which could be respectively disposed at the leftand right sides of the movable carrier (e.g. an inner or outer area nearthe driver seat of the movable carrier 000A, such as the front pillar,the left/right rear-view mirror, the fascia, the front windshield,etc.), so as to operate corresponding to the detection results of themovable carrier 000A.

Next, the conditions the control device 0030 decontrols the movablecarrier 000A, which follows the target carrier 000B or the lane marking000C, will be described. Any of the following conditions could be usedas the decontrol criteria:

(1) When the control device 0030 receives the state signal that thespeed of the movable carrier 000A is less than a predetermined lowspeed, the control device 0030 does not control or aborts the controlover the traveling of the movable carrier 000A. For example, thepredetermined low speed may be 10 Km/h.

(2) When the control device 0030 receives the state signal that thespeed of the movable carrier 000A is not less than a predetermined highspeed, the control device 0030 does not control or aborts the controlover the traveling of the movable carrier. For example, thepredetermined high speed is 160 Km/h. When the speed of the movablecarrier is above 160 Km/h, the control device 0030 no longer controlsthe movable carrier 000A to accelerate, or stops the movable carrier000A from following the target carrier 000B or the lane marking 000C.

(3) When the control device 0030 controls the movable carrier 000A totravel, the control device 0030 aborts the control over the traveling ofthe movable carrier 000A upon receiving one of the detection signalsthat the previously followed target carrier 000B and/or the previouslane marking 000C is no longer present in the environment image capturedin the traveling direction.

(4) The operation module 0012 detects whether there is a dodging carrier000D between the target carrier 000B and the movable carrier 000A in theenvironment image captured in the traveling direction and generates acorresponding detection signal. For example, during the startup offollowing the preceding vehicle (the target carrier 000B), anothervehicle (the dodging carrier 000D) moves into the lane from the side, asshown in FIG. 1D. When the control device 0030 controls the movablecarrier 000A to travel, the control device 0030 aborts the control overthe traveling of the movable carrier 000A upon receiving the detectionsignal that the dodging carrier 000D is between the target carrier 000Band the movable carrier 000A, so as to avoid the movable carrier 000Afrom colliding with the dodging carrier 000D.

(5) The state detecting device 0020 could further detect the actuationof a brake pedal of the movable carrier 000A, and the detected movingstate includes at least whether the brake pedal is operated. When thecontrol device 0030 controls the movable carrier 000A to travel, thecontrol device 0030 aborts the control over the traveling of the movablecarrier 000A upon receiving the state signal that the brake pedal isoperated.

(6) The operation module 0012 further detects the distance between thetarget carrier 000B and the movable carrier 000A, and then generates acorresponding detection signal, in which the operation module 0012 couldjudge the distance from the environment image, thereby generating thecorresponding detection signal, but is not limited thereto. A method ofdetermining the distance using the detection wave will be describedlater. The control device 0030 further calculates the moving speed ofthe target carrier 000B according to the state signal and the detectionsignal. When the speed of the target carrier 000B calculated by thecontrol device 0030 is less than a decontrol speed, and a detectionsignal that the distance between the target carrier 000B and the movablecarrier 000A is less than a decontrol distance is received, the controldevice 0030 aborts the control over the traveling of the movable carrier000A.

In this embodiment, the state detecting device 0020 could further detectthe operation of a driving pedal of the movable carrier 000A. After thecontrol device 0030 aborts the control over the traveling of the movablecarrier 000A, when the speed of the target carrier 000B calculated bythe control device 0030 is faster than the decontrol speed, and thedetection signal that the distance between the target carrier 000B andthe movable carrier 000A is greater than the decontrol distance as wellas the state signal that the driving pedal is operated are received, thecontrol device 0030 then controls the movable carrier to travel in amanner that follows the target carrier 000B.

Further, after the control device 0030 aborts the control over thetraveling of the movable carrier 000A, the control device 0030 generatesa warning message upon receiving the detection signal that the distancebetween the target carrier 000B and the movable carrier 000A is greaterthan the decontrol distance when the speed of the target carrier 000Bcalculated by the control device 0030 is faster than the decontrolspeed.

In any of the above manners, when the control device 0030 aborts thecontrol over the movable carrier 000A, the control device 0030 controlsthe warning device 0040 to generate a warning message to prompt thedriver that the control over the movable carrier 000A has been aborted.

In this embodiment, the operation module 0012 further detects thedistance between the target carrier 000B and the movable carrier 000A,and generates the detection signal. The control device 0030 furthercalculates the moving speed of the target carrier 000B according to thestate signal and the detection signal, and when the control device 0030receives the detection signal that there is the target carrier 000B inthe environment image, the control device 0030 controls the movablecarrier 000A to follow the target carrier 000B at nearly the movingspeed equal to or close to that of the target carrier 000B.

In this embodiment, with reference to FIG. 1E, when the control device0030 receives the detection signal that there is not the target carrier000B in the environment image but there is the lane marking 000C in theenvironment image, the control device 0030 controls the movable carrier000A to follow the lane marking 000C at a cruising speed.

In practice, the movable carrier 000A could be controlled in conjunctionwith the starting speed. More specifically, the moving state detected bythe state detecting device 0020 includes at least the moving speed ofthe movable carrier 000A. When the control device 0030 receives thedetection signal that there is not the target carrier 000B in theenvironment image but there is the lane marking 000C in the environmentimage and the state signal that the moving speed of the movable carrier000A is faster than a starting speed, the control device 0030 controlsthe movable carrier 000A to follow the lane marking 000C at a cruisingspeed, which is faster than the starting speed. The starting speed maybe, for example, 10 Km/h.

In order to change the cruising speed, the movable carrier auxiliarysystem 0001 of the present embodiment further includes an adjustingdevice 0050 electrically connected to the control device 0030 foroutputting an adjustment signal to the control device 0030 in order toincrease or decrease the cruising speed. The adjusting device 0050 couldbe provided, for example, on the steering wheel of the movable carrier000A for the driver to control.

During the traveling of the movable carrier 000A at the cruising speed,the operation module 0012 further detects whether there is a dodgingcarrier 000D traveling along the lane marking line 000C in theenvironment image captured in the traveling direction as well as thedistance between the dodging carrier 000D and the movable carrier 000A.The warning device 0040 is adapted to issue a warning message when theoperation module 0012 detects that there is the dodging carrier 000D inthe environment image captured in the traveling direction and thedistance between the dodging carrier 000D and the movable carrier 000Ais less than a predetermined distance.

In addition to determining the distance between the target carrier 000Band the movable carrier 000A or the distance between the target carrier000B and the dodging carrier 000D by the environment image, theenvironment detecting device 0010 further includes a detection wavetransceiver module 0013 electrically connected to the operation module0012. The detection wave transceiver module 0013 sends a detection wavein at least the traveling direction of the mobile carrier 000A, andreceives a reflected detection wave. The aforementioned detection wavemay be an ultrasonic wave, a millimeter-wave radar, a lidar, infraredlight, a laser, or a combination thereof. The operation module 0012detects the distance between the target carrier 000B and the movablecarrier 000A in the environment image through the environment image andthe reflected detection wave, and generates the corresponding detectionsignal. The operation module may also determine the distance between thetarget carrier 000B and the movable carrier 000A only by the reflecteddetection wave.

In practice, there may also be two image capturing modules 0011, whichchoose different depths of field to capture the environment images. Theoperation module 0012 detects whether there is the target carrier 000Bor the lane marking 000C in the traveling direction as well as adistance between the target carrier 000B or the lane marking 000C andthe movable carrier 000A through a stereoscopic environment imagecomposed of the environment images captured by the two image capturingmodules 0011, and generates the detection signal.

In order to maintain the distance between the movable carrier 000A andthe target carrier 000B, in the embodiment, when the control device 0030receives the detection signal that there is the target carrier 000B inthe environment image captured in the traveling direction, the controldevice 0030 controls the movable carrier 000A to travel in a manner ofreducing a moving speed of the movable carrier 000A if the distancebetween the target carrier 000B and the movable carrier 000A is lessthan a following distance, and the control device 0030 controls themovable carrier 000A to travel in a manner of increasing the movingspeed if the distance between the target carrier 000B and the movablecarrier 000A is greater than the following distance. In this way, thepurpose of keeping following distance is achieved.

The adjusting device 0050 could also output an adjustment signal to thecontrol device 0030 to increase or decrease the following distance. Forexample, the driver may operate the adjusting device 0050 to change thefollowing distance.

The movable carrier auxiliary system 0001 of the present embodimentfurther includes a global positioning device 0060 and a road map unit0070, both of which are electrically connected to the control device0030. The global positioning device 0060 is disposed at the movablecarrier 000A and continuously generates and outputs a global positioninginformation. The road map unit 0070 is disposed at the movable carrier000A and stores a plurality of road data, each of which includes atleast one lane datum having geometric information of a lane marking000C. The control device 0030 continuously receives the globalpositioning information and continuously compares the received globalpositioning information with the lane data to find a matched lane datumcorresponding to the received global positioning information. Thecontrol device 0030 captures the geometric information of the lanemarking 000C of the matched lane datum, thereby controlling the movablecarrier 000A to travel at the cruising speed following the capturedgeometric information.

The movable carrier auxiliary system 0001 of the present embodimentfurther includes a display device 0080 electrically connected to theenvironment detecting device 0010 for displaying whether there is thetarget carrier 000B or the lane marking 000C in the environment imagecaptured in the traveling direction. When the control device 0030controls the movable carrier 000A to travel, the display device 0080displays a vehicle icon if there is the target carrier 000B in theenvironment image captured in the traveling direction; and the displaydevice 0080 displays a lane icon if there is the lane marking 000C inthe environment image captured in the traveling direction.

The display device 0080 may also be electrically connected to the statedetecting device 0020 to display the moving state of the movable carrier000A.

FIG. 1F is a schematic perspective view showing a display device 0080according to the first system embodiment of the present invention, inwhich the display device 0080 is a vehicle electronic rear-view mirror0100 having a display (not shown), for example. FIG. 1G is a schematicsection view taken along the short side of the display device of FIG.1F. The vehicle electronic rear-view mirror 0100 could be disposed on amovable carrier, e.g. a vehicle, to assist in the driving of the vehicleor to provide information about driving. More specifically, the vehicleelectronic rear-view mirror 0100 could be an inner rear-view mirrordisposed inside the vehicle or an outer rear-view mirror disposedoutside the vehicle, both of which are used to assist the driver inunderstanding the location of other vehicles. However, this is not alimitation on the present invention. In addition, the movable carrier isnot limited to the vehicle, and could be other types of transportation,such as a land train, an aircraft, a water ship, etc.

The vehicle electronic rear-view mirror 0100 is assembled in a casing0110, wherein the casing 0110 has an opening (not shown). Morespecifically, the opening of the casing 0110 overlaps with a reflectivelayer 0190 of the vehicle electronic rear-view mirror 0100 (as shown inFIG. 1F). In this way, external light could be transmitted to thereflective layer 0190 located inside the casing 0110 through theopening, so that the vehicle electronic rear-view mirror 0100 functionsas a mirror. When the driver drives the vehicle and faces the opening,for example, the driver could perceive the external light reflected bythe vehicle electronic rear-view mirror 0100, thereby knowing theposition of the rear vehicle.

Referring to FIG. 1G, the vehicle electronic rear-view mirror 0100includes a first transparent assembly 0120 and a second transparentassembly 0130, wherein the first transparent assembly 0120 faces thedriver, and the second transparent assembly 0130 is disposed on a sideaway from the driver. More specifically, the first transparent assembly0120 and the second transparent assembly 0130 are translucentsubstrates, wherein a material of the translucent substrates could beglass, for example. However, the material of the translucent substratesis not a limitation on the present invention. In other embodiments, thematerial of the translucent substrates could be plastic, quartz, PETsubstrate, or other applicable materials, wherein the PET substrate hasthe advantages of low cost, easy manufacture, and extremely thinness, inaddition to the packaging and protection effects.

In this embodiment, the first transparent assembly 0120 includes a firstincidence surface 0122 and a first exit surface 0124, wherein anincoming light image from the rear of the driver enters the firsttransparent assembly 0120 via the first incidence surface 0122, and isemitted via the first exit surface 0124. The second transparent assembly0130 includes a second incidence surface 0132 and a second exit surface0134, wherein the second incidence surface 0132 faces the first exitsurface 0124, and a gap is formed between the second incidence surface0132 and the first exit surface 0124 by an adhesive 0114. After beingemitted via the first exit surface 0124, the incoming light image entersthe second transparent assembly 0130 via the second incidence surface0132 and emitted via the second exit surface 0134.

An electro-optic medium layer 0140 is disposed in the gap between thefirst exit surface 0124 of the first transparent assembly 0120 and thesecond incidence surface 0132 of the second transparent assembly 0130.At least one transparent electrode 0150 is disposed between the firsttransparent assembly 0120 and the electro-optic medium layer 0140. Theelectro-optic medium layer 0140 is disposed between the firsttransparent assembly 0120 and at least one reflective layer 0190. Atransparent conductive layer 0160 is disposed between the firsttransparent assembly 0120 and the electro-optic medium layer 0140.Another transparent conductive layer 0160 is disposed between the secondtransparent assembly 0130 and the electro-optic medium layer 0140. Anelectrical connector 0170 is electrically connected to the transparentconductive layer 0160, and another electrical connector 0170 iselectrically connected to the transparent electrode 0150, which iselectrically connected to the electro-optic medium layer 0140 directlyor indirectly through the another transparent conductive layer 0160,thereby transmitting electrical energy to the electro-optic medium layer0140 to change a transparency of the electro-optic medium layer 0140.When a luminance of the incoming light image exceeds a certain luminance(e.g. strong light from the headlight of the rear vehicle), a glaresensor 0112 electrically connected to a control member 0180 receives thelight energy and convert it into a signal, and the control member 0180determines whether the luminance of the incoming light image exceeds apredetermined luminance, and if a glare is generated, the electricalenergy is provided to the electro-optic medium layer 0140 by theelectrical connector 0170 to generate an anti-glare performance.Generally, if the incoming light image has a strong luminance, the glarecould be generated and thus affects the driver's line of sight, therebyendangering the driving safety.

In addition, the transparent electrode 0150 and the reflective layer0190 may respectively cover the entire surfaces of the first transparentassembly 0120 and the second transparent assembly 0130. However, this isnot a limitation on the present invention. In this embodiment, thetransparent electrode 0150 may use a material selected from metaloxides, such as indium tin oxide, indium zinc oxide, aluminum tin oxide,aluminum zinc oxide, indium antimony zinc oxide, or other suitableoxides, or a stacked layer composed of at least two of the foregoingoxides. Moreover, the reflective layer 0190 may be conductive and madeof a material selected from the group consisting of silver (Ag), copper(Cu), aluminum (Al), titanium (Ti), chromium (Cr), molybdenum (Mo), andan alloy thereof, or contains silicon dioxide or a transparentconductive material. However, the material of the transparent electrode0150 and the material of the reflective layer 0190 are not limitationson the present invention. In other embodiments, the material of thetransparent electrode 0150 and the material of the reflective layer 0190could be other types of materials.

The electro-optic medium layer 0140 could be made of an organic materialor an inorganic material. However, this is not a limitation on thepresent invention. In the current embodiment, the electro-optic mediumlayer 0140 could be an electrochromic material. The electro-optic mediumlayer 0140 is disposed between the first transparent assembly 0120 andthe second transparent assembly 0130 and also disposed between the firsttransparent assembly 0120 and the reflective layer 0190. Morespecifically, the transparent electrode 0150 is disposed between thefirst transparent assembly 0120 and the electro-optic medium layer 0140(i.e., the electrochromic material layer). In an embodiment, thereflective layer 0190 could be disposed between the second transparentassembly 0130 and the electro-optic medium layer 0140. In addition, inthe current embodiment, the vehicle electronic rear-view mirror 0100further includes an adhesive 0114 located between the first transparentassembly 0120 and the second transparent assembly 0130 and surroundingthe electro-optic medium layer 0140. The electro-optic medium layer 0140is co-packaged by the adhesive 0114, the first transparent assembly0120, and the second transparent assembly 0130.

In the current embodiment, the transparent conductive layer 0160 isdisposed between the electro-optic medium layer 0140 and the reflectivelayer 0190. More specifically, the transparent conductive layer 0160could be used as an anti-oxidation layer of the reflective layer 0190,so that the electro-optic medium layer 0140 could be prevented fromdirect contact with the reflective layer 0190, thereby preventing thereflective layer 0190 from being corroded by the organic materials, andextending the service life of the vehicle electronic rear-view mirror0100 of the current embodiment. In addition, the electro-optic mediumlayer 0140 is co-packaged by the adhesive 0114, the transparentelectrode 0150, and the transparent conductive layer 0160. In thecurrent embodiment, the transparent conductive layer 0160 contains amaterial selected from the group consisting of indium tin oxide (ITO),indium zinc oxide (IZO), Al-doped ZnO (AZO), fluorine-doped tin oxide,and a combination thereof.

In the current embodiment, the vehicle electronic rear-view mirror 0100may be optionally provided with the electrical connector 0170. Forinstance, in an embodiment, the electrical connector 0170 may be aconducting wire or a conducting structure electrically connected to thetransparent electrode 0150 and the reflective layer 0190, so that thetransparent electrode 0150 and the reflective layer 0190 could beelectrically connected to the at least one control member 0180, whichprovides a driving signal via the conducting wire or the conductingstructure, thereby driving the electro-optic medium layer 0140.

When the electro-optic medium layer 0140 is enabled, the electro-opticmedium layer 0140 would undergo an electrochemical redox reaction andchange its energy level to be in a diming state. When external lightpasses through the opening of the casing 0110 and reaches theelectro-optic medium layer 0140, the external light would be absorbed bythe electro-optic medium layer 0140 which is in the diming state, sothat the vehicle electronic rear-view mirror 0100 is switched to ananti-glare mode. On the other hand, when the electro-optic medium layer0140 is disenabled, the electro-optic medium layer 0140 is transparent.At this time, the external light passing through the opening of thecasing 0110 passes through the electro-optic medium layer 0140 to bereflected by the reflective layer 0190, so that the vehicle electronicrear-view mirror 0100 is switched to a mirror mode.

More specifically, the first transparent assembly 0120 has the firstincidence surface 0122 which is away from the second transparentassembly 0130. For instance, external light from the rear vehiclesenters the vehicle electronic rear-view mirror 0100 via the firstincidence surface 0122, and then the vehicle electronic rear-view mirror0100 reflects the external light such that the external light leaves thevehicle electronic rear-view mirror 0100 via the first incidence surface0122. In addition, eyes of the vehicle driver could receive the externallight reflected by the vehicle electronic rear-view mirror 0100 to knowthe position of other vehicles behind. Moreover, the reflective layer0190 could have the optical property of partial transmission and partialreflection by selecting a suitable material and designing a proper filmthickness.

The display of the vehicle electronic rear-view mirror 0100 may be anLCD or an LED, and the display may be disposed inside or outside thecasing 0110, for example, on the side of the second transparent assembly0130 away from the first transparent assembly 0120, or on the secondexit surface 0134 of the second transparent assembly 0130 away from thefirst transparent assembly 0120. Since the reflective layer 0190 has theoptical property of partial transmission and partial reflection, theimage light emitted by the display could pass through the reflectivelayer 0190, thereby allowing the user to view the internal imagedisplayed by the display so as to display the warning message.

With reference to FIGS. 1H and 1I, FIG. 1H is a block diagram of amovable carrier auxiliary system 0002 according to a second systemembodiment of the present invention, and FIG. 1I is a schematic viewshowing the operation of the movable carrier 000A applied to the secondsystem embodiment of the present invention.

The movable carrier auxiliary system 0002 of the present embodiment hassubstantially the same configuration as that of the first systemembodiment, except that the environment detecting device 0010 has threeimage capturing modules 0011 electrically connected to the operationmodule 0012. Referring to FIG. 1I, the image capturing modules 0011 arerespectively disposed at the front side, the left side, and the rightside of the movable carrier 000A for capturing and generating theenvironment images in the forward, leftward, and rightward directions ofthe movable carrier 000A. In this embodiment, the front side of themovable carrier 000A may be, for example, the front side of the vehicle,the vicinity of the front windshield in the vehicle, or the side of thefront bumper; the left side could be, for example, a left rear viewmirror; and the right side may be, for example, a right rear viewmirror. The horizontal view angle of each of the image capturing modulesfor capturing the environmental images in the leftward and rightwarddirections is at least 180 degrees, so that the detection range could beextended to the front and rear of the left and right sides.

The image capturing module 0011 disposed at the front side of themovable carrier 000A is configured to capture the environment image ofthe movable carrier 000A in the traveling direction, and the two imagecapturing modules 0011 disposed respectively at the left and right sidesof the movable carrier 000A are configured to capture the environmentimages of the movable carrier 000A in the non-traveling direction. Theoperation module 0012 further detects whether there is a dodging carrier000D in the environment image captured in the non-traveling direction.In this embodiment, the operation module 0012 detects whether there is adodging carrier 000D (for example, a car coming from the left or rightside) in the environment images captured in the left and rightdirections of the movable carrier, and generates the correspondingdetection signal. The control device 0030 controls the movable carrier000A to follow the target carrier 000B or the lane marking 000Caccording to the detection signal and the state signal and to travel ina manner not to approach the dodging carrier 000D.

The operation module 0012 further calculates a distance between thedodging carrier 000D and the movable carrier 000A in the non-travelingdirection, determines whether the distance is less than a safe distanceor not, and generates the corresponding detection signal. When theoperation module 0012 generates the detection signal of less than thesafety distance, the operation module 0012 causes the warning device0040 to issue the warning message.

The detection wave transceiver module 0013 of this embodiment furtherincludes sending a detection wave in the non-travel direction of themovable carrier 000A and receiving the reflected detection wave. Theoperation module 0012 further detects whether there is a dodging carrier000D in the non-traveling direction of the movable carrier 000A throughthe reflected detection wave. The control device 0030 controls themovable carrier 000A to travel in a manner to follow the target carrier000B or the lane marking 000C but not to approach the dodging carrier000D according to the detection signal and the state signal.

In practice, there may be two or more image capturing modules 0011,which are respectively used for capturing the environment images in thetraveling direction and the non-traveling direction of the movablecarrier 000A.

Referring to FIG. 1J and FIG. 1K, FIG. 1J is a block diagram of amovable carrier auxiliary system 0003 according to a third systemembodiment of the present invention, and FIG. 1K is a schematic viewshowing the operation of the movable carrier 000A applied to the thirdsystem embodiment of the present invention. The difference between thesecond and third system embodiments lies in that the third embodimentuses four image capturing modules 0011, which are respectively disposedat the front side, the left side, the right side, and the rear side ofthe movable carrier 000A, and the rear side of the movable carrier 000Amay be, for example, the side of the rear compartment or the side of therear bumper. The image capturing module 0011 at the rear side is used tocapture the environment image in the backward direction of the movablecarrier 000A. The operation module 0012 detects whether there is atleast one of the target carrier 000B and the lane marking 000C in theenvironment images captured by the image capturing modules 0011 togenerate the corresponding detection signal.

In an embodiment, the lenses of high Abbe number and the lenses of lowAbbe number are arranged in an interlaced arrangement that could behelpful for correction of aberration of the optical image capturingsystem.

An equation of aspheric surface is

z=ch ²/[1+[1(k+1)c ² h ²]^(0.5)]+A4h ⁴ +A6h ⁶ +A8h ⁸ +A10h ¹⁰ +A12h ¹²+A14h ¹⁴ +A1 6h ¹⁶ +A18h ¹⁸ +A20h ²⁰+  (1)

where z is a depression of the aspheric surface; k is conic constant; cis reciprocal of the radius of curvature; and A4, A6, A8, A10, A12, A14,A16, A18, and A20 are high-order aspheric coefficients.

In the optical image capturing system, the lenses could be made ofplastic or glass. The plastic lenses may reduce the weight and lower thecost of the optical image capturing system, and the glass lenses maycontrol the thermal effect and enlarge the space for arrangement of therefractive power of the optical image capturing system. In addition, theopposite surfaces (object-side surface and image-side surface) of thefirst to the seventh lenses could be aspheric that could obtain morecontrol parameters to reduce aberration. The number of aspheric glasslenses could be less than the conventional spherical glass lenses, whichis helpful for reduction of the height of the optical image capturingsystem.

Furthermore, in the optical image capturing system provided by thepresent invention, when the lens has a convex surface, it means that thesurface of the lens around the optical axis is convex, and when the lenshas a concave surface, it means that the surface of the lens around theoptical axis is concave.

The optical image capturing system of the present invention could beapplied in a dynamic focusing optical image capturing system. It issuperior in the correction of aberration and high imaging quality sothat it could be allied in lots of fields.

The optical image capturing system of the present invention couldfurther include a driving module to meet different demands, wherein thedriving module could be coupled with the lenses to move the lenses. Thedriving module could be a voice coil motor (VCM), which is used to movethe lens for focusing, or could be an optical image stabilization (OIS)component, which is used to lower the possibility of having the problemof image blurring which is caused by subtle movements of the lens whileshooting.

To meet different requirements, at least one lens among the first lensto the seventh lens of the optical image capturing system of the presentinvention could be a light filter, which filters out light of wavelengthshorter than 500 nm. Such effect could be achieved by coating on atleast one surface of the lens, or by using materials capable offiltering out short waves to make the lens.

To meet different requirements, the image plane of the optical imagecapturing system in the present invention could be either flat orcurved. If the image plane is curved (e.g., a sphere with a radius ofcurvature), the incidence angle required for focusing light on the imageplane could be decreased, which is not only helpful to shorten thelength of the optical image capturing system (TTL), but also helpful toincrease the relative illuminance.

The seventh lens 270 has negative refractive power and is made of glass.An object-side surface 272, which faces the object side, is a convexsurface, and an image-side surface 274, which faces the image side, is aconvex surface. It may help to shorten the back focal length to keepsmall in size, and may reduce an incident angle of the light of anoff-axis field of view and correct the aberration of the off-axis fieldof view.

The infrared rays filter 280 is made of glass and is disposed betweenthe seventh lens 270 and the image plane 290. The infrared rays filter280 gives no contribution to the focal length of the optical imagecapturing system 20.

The third lens 330 has positive refractive power and is made of plastic.An object-side surface 332 thereof, which faces the object side, is aconvex aspheric surface, and an image-side surface 334 thereof, whichfaces the image side, is a convex aspheric surface. The image-sidesurface 334 has an inflection point.

The fourth lens 340 has negative refractive power and is made ofplastic. An object-side surface 342, which faces the object side, is aconcave aspheric surface, and an image-side surface 344, which faces theimage side, is a concave aspheric surface. The image-side surface 344has an inflection point.

The fifth lens 350 has positive refractive power and is made of plastic.An object-side surface 352, which faces the object side, is a convexaspheric surface, and an image-side surface 354, which faces the imageside, is a convex aspheric surface.
